Abstract: The present disclosure provides sensing systems and methods that are useful for monitoring materials (e.g., cement) via light diffusion to identify characteristics thereof and changes therein. The systems can utilize a light source, a light sensor, and light transmitting members combined with the material to be monitored. In use, light from the light source can be allowed to scatter through the material via the light transmitting members for detection by the light sensor. The data regarding the light transfer can be transmitted utilizing a communication interface and can be analyzed using data processing equipment. The systems and methods may particularly be utilized in monitoring the reinforcing cement positioned between the casing and the formation in an oil well.
